As Benjamin Kabak notes:
I remember seeing this one in the subways, and at the time it was very appropriate. As you can see above, the ad plays on the MTA’s notoriously unreliable public address system. Fifteen years, the MTA swore they were working to improve the PA system. Based on what I hear on the trains and in stations every day, I’m guessing that the PA overhaul is one project not quite there yet.
